I think your real dilemma is whether your are ready to let WXH go or not. If you got involved with a new man and he became interested in you again, will that affect you? Because if it does, that's hardly fair to the new man, is it?

That said, before you even worry about involvement with a new man you might be better off to start out just dating and making friends with different men. You don't need to get "involved" with anyone just yet, especially if you think WXH might react in a way that affects you (i.e. where you might be tempted to go back to him).

Disclaimer: Just in case anyone jumps on my because I'm slanting this away from M recovery, I'm basing this on the thread title that she's ready to move on. It looks more like she's ready to "think" about moving on rather than actually doing it.
